Got the pump fully charged (green battery indicator) and used it twice to charge motorcycle tyres. Today the green battery died, the indicator turned orange, so I connected the device to the computer with a USB-C cable for charging. β’ First, the battery indicator started flashing green. β’ After about 1 hour of charging, the battery indicator went out and started flashing red. β’ Then it started flashing orange for a few minutes and then turned red again. β’ After 4 hours, the battery indicator continues to flash red and there is no charge. I then unplugged the USB-C cable and tried charging from the USB port on my laptop, to no avail. The device is dead. It does not hold a charge.
